Specification of Lettrsl 'atent. I Patented Mayli, 1915.

Application filed January 2, 1914. Seria1'No..810,040. v

To all whom it may concern:

-Be it known that I, VVILLIAM' J. HICKEY, a citizen of the United States, residing in the city and county of San Francisco,btate of California, have invented certain new and useful Improvements in Cooling Attachments for Radiators; and I do declare the following to be a clear, full, and exact description of the same, such as-will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in cooling attachments for radiators, the object of the invention being to produce an attachment carried by the cap of the radiator by means of which the steam generated in the radiator will pass into such attachment where it will be cooled and condensed back into the radiator. The purpose of this is to prevent the rapid evaporation of the water from the radiator and at thesame time to aid in keeping the explosive-motor, to which the radiator is usually attached, cooled to a greater degree than where my improvement is not sed.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly elfective for the purposes for which it is designed.

These objects, I accomplislrby means of such structure and relative arrangement of the parts as Will fully appear by a perusal of the following specification and claims.

On the drawings, similar characters of reference indicate corresponding parts in the several views.

Figure 1 is a front elevation of a fragmentary portion of a radiator showing the upper part broken away and in section to illustrate the application of my improved attachment to the radiator. Fig. 2 is a sectional view of the radiator cap and my improved attachment mounted thereon Referring now more particularly to the characters of reference on the drawings, the

numeral 1 designates the radiator cap which is removable in the usual manner.

,My improved attachment comprises a chambered member 2 suspended within the cap 1 and provided with an opening 3 at its lower end which communicates-from the interior of the radiator'tothe interior of the movable over the tube 6 and is .provided with an opening 9 adapted toregister with the opening 7 or such cap 8 can be turned to close said 0 ening 7. r

The cham ered member 2 is provided with an opening 10 in each side, therebeing a tube 11 communicating from one of said openings to the other and passing through the chambered member 2. One of these openings 10 would be disposed in "the direction toward which the vehicle carryingthe radiator would be moving so that there would be a continuous passage of air through the openings 10 and the tube -11. The steam escaping from the radiator 1 passes through the opening 3 into the chambered member 2 and around the tube 11. The cold air passes through the tube 11 and tends to cool and condense the steam so that it can pass back into the radiator as water. If a large volume of steam passes through the member 3 at one time so that it cannot all condense in the member 2, it will pass through the opening 5 into the chambered member 4 which, having a surface exposed to the outer cold air, will likewise tend to cool and condense the said stean1.- Excess pressure of air or steam can pass out through the opening 7 or in extremely cold weather, the opening 7 may be closed to confine the steam and heated air to aid in preventing the water from freezing in the radiator.

From the foregoing description it will readily be seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice, such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claim.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:

A device of the character described comprising the combination with a radiator cap,'

of a chambered member on the outside of said cap, said cap being provided with a passageway communicating from one of said chambered members to the other, said chambered member inside of said cap being provided with an opening in its lower end and with a pair of, openings communicating to the outside of said cap, and a tube communicating with said last named openings and I WILLIAM J.
